Please make sure you also fill out the checklist when opening a pull request. This not only ensures you went through the steps to submitting quality code, but helps us understand what has been done and what still needs work. It's ok to not have everything done, we just want to know the progress that has been made especially if someone else wants to work on this in the future.

While this is logically correct, this code block uses duplicate code for each direction. I recommend iteration through each direction in a for loop rather than copy pasting the code four times.

Some pseudocode that might help:

import java.awt.Point;

List<Point> directions = { new Point(-1, 0), new Point(1, 0), new Point(0, -1), new Point(0, 1) };

for (Point direction : directions) {
    NurikabeCell cell = destBoardState.getCell(loc.x + direction.x, loc.y + direction.y);
    
    // avoid redundant nested clauses
    if (cell != null && (...) {
        // apply logic
    }
}

Changes look good. I made a quick change to simply directions to one line, but everything else looks solid.
